WINDOW-SASH,

Specification of Letters Patent.

lPatented June yiii.

Application iled. February 16, 1914;. Serial Noy 819,058.

To all @07m/m. it may concern Be it lnown that l, FRED F. MCCLAiN, a citizen of the United States, residing at Xenia, in the county of Greene and State of 0hio, have invented certain new and useful llmprovements in Window-Sashes, of which the fol-lowing is a specification.

My invention relates to storm fronts for vehicles and more particularly to a swinging window sash adapted to form a part of such storni front but which is also suitable for use in residences 'or factories or other constructions. V

rlhe object of the invention is to'simplify the structure as well as the means and mode of operation of such devices, whereby they will not only be cheapened in construction, but will be more eflicient in use, positive in their action, vair and watertight and unlikely to get out of repair.

il further object of the inventionpis to provide a window sash which in its closed position will fit the frame sufficiently close to prevent rattle or chatter as the vehicle travels over a rough roadway and at the saine time being capable of being easily and quickly withdrawn from closedposition.

l further object of the invention is to provide a window so constructed as to prevent the seepage of water inward over the sill.

With the above primary and otherinci- Afully appear in the specification, the. invention consists of the features of construction, the parts and combinations thereof and the mode of operation or their equivalents as hereinafter described and set forth in the claims.

Referring to the drawings, Figure l is a perspective View of a portion'of a vehicle to which a storm front embodying the swinging window sash forming the subject matter hereof, has been applied. Fig. 2 is a perspective view of a swinging sash window in open position, viewedy from the inside. the swinging window sash showing by dotted and dot and dash lines the window adjusted to different positions. Fig 4c is a transverse sectional view of the window sash in its closed position. Fig. 5 is an enlarged transverse sectional View of one of the side bars of the window frame.

Lilie parts are indicated by similar char- Ving sash 2 is hinged at 3 Fig. 3 is a vertical sectional view of l acters of; reference throughout the several views.

In the drawings, l is a storni front of the vehicle embodying the swinging sash 2 forining the subject matter hereof. The swingalong its upper edge to the frame 4. rlhe sash and frame are preferably though not necessarily correspondingly rabbeted as indicated at 5 on the opposite vertical sides and if desired, across the top as shown in Figs. 3 and 4. It is not necessary that the frame and sash should be rabbeted upon their top edges even though the side rabbets are employed. The joint between the sash and frame is preferably protected upon the outside of the frame by weather strips G secured to the frame and overlapping the sash. These weather strips will prevent the rain beating through the crevices between the sash and frame even though the rabbets 5 are omitted. Y

The sill 7 of the'frame l is beveled downward and outward as indicated at`8.y This bevel may be of any desired angle, but it has been found in practice most convenient and desirable to form the-bevel at an angle of substantially forty five degrees. 'lhe lower edge of the swinging sash 2 is beveled downward and outward as indicated at 9. Hinged to the lower edge of the sash 2 in such manner as to swing toward the outer side of the sash and in a direction the reverse of the movement of the sash 2 about its hinged connections 3,v is a transverse strip l0, beveled on its upper edge ll to correspond with the downward and outward inclination of the lower beveled edge 9 of the swinging sash and beveled on its lower edge l2 to correspond with the downward and outward beveled sill of the frame. A

It is to be noted that the swinging sash 2 and the transverse strip l0 hinged thereto form a structure resembling and operating as a toggle link and further that the swinging sash approaches the sill 7 from the high side of the bevel 8. The swinging sash with the attached strip 10 is of such length that they can not pass over the high side of the .beveled sill until the strip l0 is oscillated'as shown by dotted lines in Fig. 3. The flexing of the transverse strip 10 about its hinged connection with the swingingsash permits the lower beveled edge 12 of the strip to pass over the high side of the sill 7, whereupon by pressing the sash 2 outward,

lll@

thesash is tightened in the frame by the 'toggle action of the sash 2 and sti-1p l() to prevent the rattle or chatter of the sash within the frame.A l`By the toggle action, thel sash is further firmly seated on the top or cap of the frame anden the beveled face 11 Vof the strip 10, which in turn is firmly seat-k ed on the beveled sill 7 to exclude water and air from said joints.

VJ hen the sash and strip have been adjusted to a position upon a deadv center or v position.

when the sash is in a plane common with the.v strip, the parts will retain their adjusted positions without the necessity of. other locking means. I-Iowever by providing slight clearancefor the sash, whereby the sash and sash,- a slight pressure upon'the outer side of the device'adjacent to the hinged connectionof the strip 1 0 to .the-sash 2 will re lease. the sash, the strip-10 swinging upward to c lear the upper edgeof the beveled sill 7,

whereupon the sash and strip may Vbe oscilflatedrupward to. a position as indicated by dot land dash lines, where they can beheld by asuitable spring catch i3. It will thus 'be seen that the window be readily released from the-exterior of the vehicle with- ,outjthe necessity of climbing inside, which is aconvenience when the vehicle -is'in stor- -age or when hitching a horse thereto.

Under ordinary conditions it will be i found that lthe tension to which the sash and strip are subjected by their toggle like actionin the closingoperation will be sufficient to prevent rattle or chatter within the frame. `However if found' desirable L shaped spring fingers 14 maybe provided on v the frame v4 `on opposite sides of the swinging sash 2, preferably at a point cojincident with the beveled joint 9-11 of the sash2 and the strip.1;0. These spring fingers by projecting between the sash and frame prevent side movement of the sash and thereby obviate any chatter. The joint 19--11 between the sash 2 and the strip 10 and a joint 8 12 between the strip 10 and the sill 7 being inclined downward and outward, obviates any tendency of rain to seep through these joints to the inside of the vehicle.V 1

yVihile the invention is herein shown and Vdescribed as a part of a storm front for vehicles, it is to be understood that it is not rlimited to such use, but may be employed for window construction generally, and is equally applicable to building constructions. Furthermore the sash might be arranged to swing on a vertical axis without changing the construction other than to turn the.

Y frame on its side. In such case the swinging section which oscillates about an axis parallel with that of the sash, will engage a 'vertical side of the frame. The portion of the frame so engaged is to be considered as included in the term sill as herein used. I therefore do not wish to be understood as limiting the invention to its use with vehicles.

From the above description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrangement of parts, without dej'iarting from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to any specific details, but that the means and construction herein described comprise but one mode ofv putting the invention into effect, and the invention is therefore claimed broadly in any of its possible forms or modifications within the scope of the appended claims.

Having thus described my invention, I claim;

l. A window comprising a frame provided with a beveled sill, a sash oscillating about an axis parallel with the beveled sill and swinging to and from the side of the sill opposite the bevel face thereof, said sash beingv of greater extent than the opening of the frame and having a beveled edge to engage the beveled face of the sill and a Yflexible joint in the sash permitting the beveled edge thereof to be passed over the sill into engagement with the beveled face thereof.

2. A window comprising a frame having a downwardly and outwardly beveled sill, a sash oscillating about an axis parallel with the beveled sill having a downwardly and outwardly beveled free edge, a swinging section hinged to the sash having a downwardly and outwardly beveled top edge engaging with the beveled edge of the sash Y and a downwardly and outwardly beveled bottom edge engaging with the beveled sill.

3. A window comprising a frame, a sash comprising two sections hinged one to the other and occupying a substantially common plane when in closed position, and downwardly and outwardly beveled joints between the sash sections and between the sash and frame.

4. In a window construction, a frame having a beveled sill, a sash hinged to the frame cap, said .sash being beveled on its having both edges beveled downward and outward to correspond with the beveled lower edge of the sash and the beveled sill.

6. A window comprising a frame, a sash hinged to the frame, a swinging section hinged to the sash, the hinged connections of the sash with the frame and the swinging section with the sash being parallel one with the other and oppositely disposed whereby said parts will swing about their respective connections in opposite directions rom normal position, the free edge of the swinging section being adapted to be engaged with the l.side of the frame opposite therhinged connection of Vthe sash, substantially as specied.

7. A downwardly and outwardly beveled sill, an inward swinging sash having a downwardly and outwardly beveled lower edge parallel with its axis of oscillation, and a iiexible joint in the sash likewise parallel with the axis of oscillation permitting the lowest edge of the sash bevel to pass over the highest edge of the bevel of the sill.

In testimony whereof, I have hereunto set Iny hand this 30th day of January7 1914.
